ElectraStim products work by stimulating your nerve endings using carefully produced electrical signals and Flick is a revolution in electro stimulation technology! The new Flick controller from ElectraStim not only has eoght built in programmes including, escalating patterns, it's also able to stimulate in rhythm with the flicking movements of the control unit. Simply flick your wrist to the beat you want to masturbate or have sex to and enjoy the rhythmic sensations. Go slow or fast, soft or hard, whatever you desire. It's also the first product of its kind to incorporate a USB re-chargeable system allowing the Flick unit to charged for 4 hours with no need for batteries! If you want to have the option of stimulating two different areas at the same time or using with a partner where they can control the intensity of their pleasure separately from you, this Duo stimulator pack is ideal as it has 2 output jacks. The Pads measure 50mm(2) square, are self adhesive and can be placed across any desirable area. You and your partner can wear one pad each on the buttock or inner thigh area and then have intercourse like you have never done before as the stimulation current flows between your two bodies! All ElectraStim accessories are of course directly compatible with the Flick stimulator. If you already have some electro stimulation accessories that have the 2mm socket then they will connect directly to the ElectraStim cable. If you have 4mm accessories you will need to get an adapter.   The ElectraStim Flick EM80 Digital Stimulator Self adhesive pads x 4 (50mm/2 square) Accessory Connecting Cable x 2 USB Charging Cable Instructions Drawstring Storage Pouch High Quality Packaging 3 Year Warranty Upgrade Registration Card
